LUMBER-DRIER.

SPECIFICATION forming part of Letters Patent No. 347,387, dated August17, 1886.

Application filed December 28, 1885. Serial No. 186,953. (No model.)

To aZZ whom it mayconcern:

Be it known that I, GEORGE W. SHARER, a citizen of the UnitedStates,residing at Terr-e Haute,in the county of Vigo and State of Indiana,have invented certain new and useful tion and utility in the arrangementof the part which will expedite the drying and-attain the best results;

The invention therefore consists of constructhe air-ducts; Fig. 5,avertical section on line as m, Fig. 2; Fig. 6, a side elevation of partof the drier, and showing the interior of the shed; Fig. 7,.an endelevation of part of the drier and the flue and chimney; Fig. 8, asection on line 3 y, Fig. 2; Fig. 9, a section on line 2 2, Fig. 8; Fig.10, a section on line 1' r, Fig. 2, and looking in the direction of thearrow 1 Fig. 11, a section on line 8 s, Fig. 10, the damper at closingthe ventilating-tube d; Fig. 12, a side elevation of one truck; Fig. 13,an end elevation of the truck shown in Fig. 12; Fig. 14, a section ofthe truck taken through the wheel; Fig. 15, a side elevation of themeans for lifting the door,and Fig. 16 an end view of the same.

A represents the furnace,having grate-bars a, the bridge-wall a uponwhich the grate-bars rest, the air-vault a covered by bars or perforatedplate c v and connected with the ashspace a by duct a and a slidingdoor, a. The furnaces (two of which are shown) are proper distributionof the air.

made of brick or other suitable material and provided with buck-staves athrough which rods a? pass to corresponding buck-staves (not shown) onthe back of the furnaces. Upon each side of the furnaces are buck--staves a", connected together by the rods c These buck-staves a and aand rods a a l bind the furnaces securely together, whi ch fur naces areprotected by the roof A.

Leading fromthe furnace are flues A fllined for part of their way withfirebrick, and extending to the soot-flue A having chimney A outside ofthe drier. This chimney is provided with a regulating-damper, A, havingrods a and a and lever a.

. In the upper wall of the furnace, immediately over the fire-box,arethe air-fines B, extending from the front of the furnace to the chamberB, having the large outlet-duct B",

which rests upon the top wall of flues A, and extends about two-thirds(t) the length of the drier, and terminating in a cross flue or duct,B", having its upper side perforated for the The duct B is of less widththan the width of all the fines A, so that heat from the latter will beradiated into the drying-chamber, as well as absorbed by the air passingthrough the ducts.

Piers O are arranged at suitable intervals on each side of fines A andeach is provided with a wooden cap, 0, and a block, 0, which rests uponcap 0 and supports the beam G,extending the whole length of the drier.At the sides of the flues are piers 0, upon which are placed the beams 0extending the whole length of the drier. Gross-beams 0* are placedacross the beams O and G and supportthe longitudinal beams 0 upon whichthe tracks 0 are laid. Between the piers O and 0* and cross-beams 0* arethe metallic partitions G which form the compartments Gflthat receiveradiated heat from the fines, and also prevent the-heat from onecompartment from passing into another. Between the tracks 0 are thepartitions (3 which are practically a continuation of the partitions Gand proj ect upwardly between the tracks to or slightly above the top ofthe trucks. These partitions O are made of rubber, felt, or otherelastic material, so that when the car is moved it will givesufficiently to permit it to pass and have at the same time contact withthe contents of the car to prevent the heated air from duct B frompassing said car or cars.

The walls of drier D are made of brick or other suitable material,embrace the furnacefiues A" and the parts above them,and capped by theroof D, which is preferably made slanting from the center to the sidesand provided with felt partitions d These partitions prevent the heatedair from the duct B from passing over the ears. At the front end of thedrier is an air-escape duct, D, for the dryingchamber. This ductisprovided with a transverse partition ,D, having the vcntilatin g-tubesI), Figs. 2, 10, and 11, each having a damper, d, operated by a rod, (1,so that the opening in the tube may be opened or closed to regulate theexit of the heated air passing from the drying-chamber.

The front and rear ends of the drier are each provided with doors,(marked, respectivcly,D and D The door D is provided with bar I), towhich is attached at each end a cable, d which pass over pulleys d on abeam, 1), and are provided with weights (1, for an obvious purpose. Therear door, 1), may be operated in the same or any other desired way.Upon the rear end of the drier is a shed, D", where the articles arecooled off before being carried away.

The trucks E (shown in detail, Figs. 12, 13, and 14) consist of twolongitudinal beams, E, joined together at their ends by cross'pieee c,and carrying the rigid axle e for the wheel 0', which is free to revolveon the axle and move longitudinally thereon, so that if there are anyinequalities in the track the load above will not be disturbed. Thesetrucks, as shown, are complete in themselves and run upon a singletrack, but take two or more of them and the load, if lumber be used, tomake the car, as shown in Fig. 8. If articles too small to extend acrossthe space between the trucks are to be dried, then planks or othermaterial can be laid across the trucks for their support. \Vhen the carhas reached the shed and it is desired to use the trucks again, they canbe easily transported from one end of the drier to the other, or thathaving the platform A.

The operation of the device is as follows: After the fires have beenstarted and the driers evenly heated by radiation from the flues A" andthe hot air admitted thereto, the cars are run into the drier throughthe front door. The heat radiated from the fines A passes upwardly tothe cars and reheats the air admitted through the air-duct, which airhas become more or less cooled by absorbing the moisture of the articlesdried. In other words, heat is added to the current of air at points togive greater efficiency to the drier. After the material has beenthoroughly dried it is passed across the compartment in which thecrossdnct is placed, to permit the contents of the ear to becomepartially cooled before passing the latter into the shed. When lumber isdried in this way no checks are made.
